RE: 2nd Gen. Drivers side leather
I got mine from Max at Five Star Ford.
The part numbers are different for each color, so unless you have a '98 with the black interior, Max will have to look it up. You'll just need to supply him with your interior color code found on the sticker on your driver's side door jamb. Or you can find it here:

EDIT: I forgot to mention that you'll also need the build date of your car. Part numbers and prices are different for cars built before and after 10/97 I believe.
The seat bottom, back, and headrest are all sold separately. I only bought the back and bottom, the head rest was fine.
I suppose you're wanting to know how much I paid...
$570 for both the seat back and bottom from Max. Retail from Ford is around $700 I believe. It's a steep price regardless, but I wanted an exact match without having to go with a complete set of leather for everything. I didn't try Torrie at FPN, so I don't know his price.
They make them on demand, so expect to wait about two weeks for it.
IMPORTANT NOTE: The seat back can ONLY be bought with a leather pocket. You WILL NOT be able to get one with a net. So if yours has a net, you'll have to do as I did and have an upholsterer remove the pocket and sew the old net onto the new leather. That cost me another $100, including having him install the seat back. He did a great job. You can't tell any difference between the DS and PS seats at all.
Here's a picture of mine. It was installed in March:

I'd suggest getting some 1/2 inch foam to build up under it. Mine's already getting some wrinkles, and I may tear it apart again and stuff some foam in there. You can get the foam at most any fabric store.
